Implementations

impl SourceState

Constructor for SourceState.

pub fn new() -> SourceState

Create a new source state with no source.

impl SourceState

Content method for SourceState.

pub fn content(&self) -> Option<&str>

Get the current content from the source.

Returns

The markdown content, or None if no source is set.

impl SourceState

Is file source method for SourceState.

pub fn is_file_source(&self) -> bool

Check if the source is file-based.

Returns

true if the source is loaded from a file, false otherwise.

impl SourceState

Line count method for SourceState.

pub fn line_count(&self) -> usize

Get the line count of the source content.

Returns

The number of lines in the source content.

impl SourceState

Reload content if the file watcher detected changes.

pub fn reload_if_changed(&mut self) -> Result<bool, Error>

Reload the source content if the watcher detected changes.

Returns Ok(true) when content changed and was reloaded.

impl SourceState

Reload source method for SourceState.

pub fn reload_source(&mut self) -> Result<bool, Error>

Reload the source content from disk (for file-based sources).

This re-reads the file. The caller should check the return value and invalidate caches if content changed.

For string-based sources, this is a no-op.

Returns

• Ok(true) - Content changed, caller should invalidate caches.
• Ok(false) - Content unchanged or source is string-based.

Errors

Returns an error if the file cannot be read.

impl SourceState

pub fn set_source_file(&mut self, path: impl AsRef<Path>) -> Result<(), Error>

Set a file-based markdown source.

This loads the file content and enables auto-reload support. Use reload_source() to check for and apply file changes.

Note: Caller should invalidate any caches after calling this.

Arguments

• path - Path to the markdown file.

Errors

Returns an error if the file cannot be read.

impl SourceState

Set source string method for SourceState.

pub fn set_source_string(&mut self, content: impl Into<String>)

Set a string-based markdown source.

Note: Caller should invalidate any caches after calling this.

Arguments

• content - The markdown content string.

impl SourceState

Source path method for SourceState.

pub fn source_path(&self) -> Option<&Path>

Get the file path if this is a file-based source.

Returns

The file path, or None if this is a string source or no source is set.

Trait Implementations

impl Clone for SourceState

fn clone(&self) -> SourceState

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SourceState

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for SourceState

Default trait implementation for SourceState.

fn default() -> SourceState

Returns the “default value” for a type.
